无法在Windows 10上通过Gradle构建Docker映像

Question

I am new to Docker and i have problems with building image from the gradle script using gradle-docker-plugin :

task dockerBuildImage(type: DockerBuildImage, dependsOn: [dockerCreateDockerfile, assemble]) {
    tag = "my_tag_here"
    dockerFile = dockerCreateDockerfile.destFile
    inputDir = dockerCreateDockerfile.destFile.parentFile
}

And than i am getting such stacktrace:

Building image using context 'D:\Learning\1\myproject\webapp\build'.
Using Dockerfile 'D:\Learning\1\myproject\webapp\build\Dockerfile'
Using tag 'localhost:5000/test/myproject-webapp:1.0.0-20170318135307' for image.

:webapp:dockerBuildImage FAILED

If i run "docker build" command directly - everything working fine. Can someone point me direction what can be wrong. Any ideas.

Answer 1

The plugin doesn't support Windows. It assumes you are running on a Linux system, because that's what Docker Engine requires. Docker for Windows uses Hyper-V virtualization (previously it relied on VirtualBox).

You'll need to run this Gradle plugin on a Linux system. That could be a VM on your Windows machine. I prefer to skip Docker for Windows; instead I run VirtualBox with a suitable Linux guest, then follow the installation instructions for Docker Engine inside that guest. Then, alongside docker in that guest, you can install gradle and any other development tools you need.
